Problems solved by technology
[0002] The well-known four-wheel all-wheel-drive vehicle steering (4WS) modes include single-wheel (zero phase) steering mode, all-wheel (reverse phase) steering mode, crab (same phase) steering mode and in-situ steering mode. On all-wheel drive vehicles, these four steering modes are hardly used, but are more used on four-wheel small construction machinery, such as skid steer loaders, which pass through the hydrostatic transmission system, through the engine, variable pump, left / right hydraulic pressure, etc. The left and right wheels are driven by the motor and sprocket mechanism. If the left and right motors work in reverse, the in-situ steering function can be realized, but the structure is complex and not suitable for four-wheel all-wheel drive vehicles.

The invention discloses a vehicle steering system and a vehicle with the same. The vehicle steering system comprises a first left steering knuckle arm, a first right steering knuckle arm and a steering gear; one end of the first left steering knuckle arm is connected with a first left steering wheel of the vehicle; one end of the first right steering knuckle arm is connected with a first right steering wheel of the vehicle; and the steering gear is provided with a first output end and a second output end, wherein the first output end is connected with the other end of the first left steering knuckle arm, the second output end is connected with the other end of the first right steering knuckle arm, and the steering gear selectively moves in the front-back direction of the vehicle. The vehicle steering system is simple in structure and capable of achieving multiple steering modes.
Description
technical field [0001] The invention relates to the field of vehicle steering, in particular to a vehicle steering system and a vehicle with the vehicle steering system.
